A new update for Gran Turismo 5, version 2.06, has just been launched and is now available for download.

The file weighs in at a hefty 475MB in size (that’s nearly half a gigabyte!), leading many to suspect it may contain a bit more than what’s outlined in the official list of changes. With Twin Ring Motegi having already been confirmed as part of the GT Academy 2012 mini-game, fans have good reason to be optimistic.

New information has also been released regarding the availability of prizes earned in the GT Academy 2012 challenges: they’ll be available on July 4, 2012, and will consist of the cars used in each round along with a special black driving suit, as seen here.

For now, here’s the official list of changes according to Polyphony Digital:

Updates and New Features

It is now possible to adjust the race BGM and sound effect volume from “Quick Options” during a race.

A save data backup feature has been added.

Compatibility for the sequential shift mode of the Guillemot “TH8 RS” gear shifter has been added.

A “Performance Difference Adjustment” has been added to the rewards for seasonal events (Applies only to seasonal events held after this update).
